Appneauon mea January 12, 192s. serial no. 246,206.

The device forming the subject Amatter of -this application is arubbersign intended to be used on the surface of ayhighwa in connectionwith traltlc signals, the liexibility of the sign permitting it to bend'Whenstruck accidentally, to the end that the vehicle striking the signmay suffer no damage, and to the end that the sign itself may not bebroken. -One object of the` invention is so l0 lto mount the` sign thatit will bend under impact, without cracking or tearing. at the placewhere it bends; and another object of the invention is to provide novelmeans for anchoring the sign in the highway. l5' It is within theprovince of the disclosure ,to improve generally andto enhance theutility of devices of that type to which the invention appertains.

With the above and other objects in .View

ceeds, the invention resides in the combina tion and arrangementof partsand in the details of construction hereinafter described and claimed, itbeing understood. .that changes in the prec-se embodiment ot' theinvention herein disclosed, may lbe made within the scope of what isclaimed, without departing from the spirit of the inven.

tion. 3o In thedrawings'z'- structed in accordance with the invention;

Figure 2 is a top plan;` I Figure 3 is an end elevation; Figure 4 is a,cross cut` onthe line 4-4 of `Figure 1, with the pavement andtheanchoring material as'added details? I e The body 1 o'f the sign is inthe form of a plate of-hard rubber which is flexible enough The lowerpart 2 of the plate 1 is ,parallell l sided, but the upperpart 3 of theplate' is tapered in width toward. its upper edge, to enhance itsiexibility. The upper lcorners 4 of the plate 1 are rounded off .to`,save the plate from damage. The lower'part 2 'of the plate .1 ismounted ina base made up of two blocks 5 of Acushion 'stock rubber vul-I .canized or Secured otherwise to opposite sides of the lower part ofthe plate 1. The

.blocks 5 fare softer and more flexiblethan the late 1, and,consequently, the plate 1 can bent back and forthin the direction whichwill appear as the description pro-V proaching Figure 1 shows inelevation, adevice con* sothat it can be bent rand twisted repeatedly.

of the arrows A in Figure 4, without'caus-v ing the plate to crack whereit .bends (at .11)

at the'upper edges of the blocks, 5. lThe plate 1 carries any kind of aninscription v10,

the word Stop being 'merely indicative of any desired marking. -Arecess7 is'formed in the highway 8 and the lower part 2 of the plate, alongwith the base blocks 5, is placed in the recess, and then a quantity ot'anchoring material 9, which ma y be asphalt, 1s poured into the recess 7on each side of the base of the sign. The anchoring material 9coalesces, as shown at12,. through staggered openings 6 in the blocks 5and in p the lower part 2 of the plate 1,- and this afords a very good4anchorage for the article.

The body 1 and\the base 5-5'of course are not on y flexible, butresilient, as well, so that they will resume the normal position andshape'attributed to theml in the drawings, after they have been bent ordis torted, by impact or otherwise.

The letters which form theinscription 'shown at l0 preferably are madeof a phosphorous compound mingled with carborun- .2. A'sign constructedin,ac,cordance with claim 1 and vfurtherl characterized by the factthatthe plate tapers in thickness from -the base toward the upper edge ofthe plate,

thereby to enhance the resiliency ot' thc'v sign'constructed inaccordance with claim 1 and further characterized the fact-that the baseand the part of the plate that is therein are supplied with anchoragevopenings. f

In testimony that I, claim thev Jiorcgo'ing as my own, I have heretoaitlxed my signature.
